The whole brain concentrations of epinephrine, norepinephrine and dopamine in North American amphibians, orders Caudata and Salientia, are reported. Epinephrine is the major catecholamine in the Salientia while norepinephrine and epinephrine concentrations are roughly equivalent in suborders of Caudata. Relative regional concentrations are similar to other classes (mammals, reptiles and birds) although the absolute concentration of epinephrine is considerably higher in amphibians than in most other species.
报告了北美有尾目和无尾目两栖动物全脑肾上腺素、去甲肾上腺素和多巴胺的浓度。肾上腺素是无尾目的主要儿茶酚胺，而去甲肾上腺素和肾上腺素的浓度在有尾目亚目中大致相当。尽管两栖动物中肾上腺素的绝对浓度比大多数其他物种高得多，但其相对区域浓度与其他类群（哺乳动物、爬行动物和鸟类）相似。
